NUT-LOCK;

Application filed November 6, 1913.

T0 (ZZZ whom it may concern:

Be it known that I, NViLLIAM WINS, Jr., a citizen of the United States, residing at Livingston, in the county of Sumter and State of Alabama, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to nut locks of that type in which the nut will be positively locked on the bolt against reverse rotation for preventing the displacement of the same due to vibration or the like.

An object of the invention resides in the provision of a nut which although retained at a desired point on the bolt from reverse rotation, nevertheless will allow for there moval of: the same from thebolt when so desired.

Other objects as well as the nature, characteristic features and scope ofmy invention will be more readily understood-from the followingdescription taken in connection with the accompanying drawings and pointed'out in the claims forming apart of this specification.

Referring to the drawings :Figure 1 is a longitudinal sectional view of the device constructed in accordance with my invention showing the same applied toa bolt; Fig. 2

.is a'perspective viewof the nut used in the present invention; Fig. 3 1s a bottom plan View of the supplemental nut used inthis invention; and'Fig. 4: is a side elevation ofthe same. r

In the drawings wherein is illustrated the preferred embodiment of this invention, a

bolt 5 is provided which is of the ordinary or any desired form, in the present instance being provided with an ordinary externally screwthreaded shank 6.

Mounted on the-threaded shank 6 of the bolt-5 is my improved nut ,7 which comprises a head '8'and an externally screw threaded sleeve 9 which is provided with internal threads 10. The head 8 of the nut 7 has mounted on the inner face thereof an elastic element 11 which in the present instance comprises a flat spring the one end of which is fixedly secured to the inner face of the head 8 while the opposite end thereof normally extends upwardly in spaced relation to the bolt 5 as shown to advantage 1n memberlZwhioh comprisesa single strand.

of wire the one end of which is fixedly engaged with the free end of the spring while the opposite end 13 thereof is bent at a right angle to the body so as to provide a handle for facilitating the actuation of said elastic element.

Adapted for threaded engagement with the threaded sleeve 9 of the nut 7 is a nut 14 which is provided with an internally threaded bore and has one face thereof ser' rated as indicated at 15 which is engaged by the free end of the fiat spring 11 so, as to prevent the dlsplacement of the same thereon. A portion 16 of the threaded sleeve-9of the'supplemental nut 7 is detached and'has one end thereof engaged in the head 8 of the nut as indicated at 17 by rivetingthe end thereof or the like, said end 17 being preferably angularlyjotfset for a purpose which will subsequently appear. The opposite end 18 of the detached portion is preferably enlarged having a portion thereof extending radially inward and provided with longi tudinally extending teeth 19 as advantageously illustrated in Fig. 3 which are adapted for biting engagement, at times, with the threadedshank 6 of the bolt,5. By angularly oifsetting the end 17 of the locking the object to be secured in the ordinarymanner, and the spacing washer 20"will thenjengage-with the element to be secured.-

The nut 14: is normally in a neutral position on said sleeve 9 ata point approximately'intermediate the ends of the'latter for a pur pose which will hereinafter be set forth. The'nut 7 is now threadedon the sh'ank6 of the bolt 5 until the inner end of said nut isengaged with the element to be secured. As

soon as the desired adjustment of the supplemental nut 7 on the bolt 5 is made the nut 14 is actuatedon the external screw threaded sleeve'9 of the nut 7 until the same engages with the spacing washer 20, as shown to advantage in Fig. 1, in which instance the teeth 19 will be forced-into biting engage ment with the externally screw threaded shank 6 of the bolt 5. During the operation of the nut leton the threaded sleeve 90f the nut 7 the elastic element 11 is in engagement with the serrations 15 allowing for the free movement of the nut on the bolt, but positively preventing the reverse rotation of the same thereon as is obvious. Should it be desired to detach the auxiliary nut 7 from its engagement with the bolt 5 force withdraw ing the handle 13 of the operating element 12 will cause the spring 11 to be disengaged from the serrations 15 allowing the nut it to be reversely turned on the threaded sleeve 9 of said auxiliary nut and threaded toward the head 8 thereof so as to allow the detached portirn 16 to take its normal posie ticn and be disengaged from its engagement with the threaded shank 6. The auxiliary nut 7 is then unthreaded from the bolt 5 in the ordinary manner.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1.
